Barrier methods
What is a barrier method?
-
A barrier method is a type of contraception which puts a barrier between the penis and vagina to keep sperm from reaching the egg.
-
Barrier methods are an effective method of contraception but are dependent on how well you use them.
-
They are not as effective as other methods such as long-acting contraceptives.
-
Condoms are the most well-known type of barrier method.
-
Some barrier methods also protect against sexually transmitted infections (STIs).
What are the different types of barrier methods?
There are three main barrier methods of contraception. These methods are:
-
External (male) condoms
-
Internal (female) condoms
-
Diaphragms & caps
Barrier methods
External (male) condom
External condoms cover an erect penis to catch sperm and prevent it from meeting & fertilising an egg.
Internal (female) condom
Internal condoms are worn inside the vagina to catch sperm and prevent it from meeting and fertilising an egg.
Diaphragms
The contraceptive diaphragm is a dome-shaped flexible disk placed in the vagina before sex.
It prevents pregnancy by blocking the entrance of the cervix, preventing sperm from reaching the womb (uterus) to fertilise an egg.
Short-acting contraception
Barrier methods are a subcategory of a larger category of contraceptives called short-acting contraception. Short acting contraceptives get their name because they work for a short period of time – either every time you have sex, daily, weekly or monthly.
